The overhanging beam is made of wood with an allowable tensile stress of σtension = 4MP a and an allowable compression stress of σcompression = −5MP a. The beam is supported by a pin at A and a roller at B.

Determine the maximum force Pmax that can be applied at the end. Hint: Calculate reaction forces in terms of P.

Calculate the shear and moment diagrams in terms of P.

Find the maximum/minimum moments in terms of P.

Adouble-strand no. 60 roller chain is used to transmit power between a 13-tooth driving sprocket rotating at 300 rev/min and a 52-tooth driven sprocket. a) what is the allowable horsepower of this drive? b) estimate the center-to-center distance if the chain length is 82 pitches. c) estimate the torque and bending force on the driving shaft by the chain if the actual horsepower transmitted is 30 percent less than the corrected (allowable) power.

The thermal expansion or contraction of a given metal is a function of the f a)-density b)-initial temperature c)- temperature difference d)- linear coefficient of thermal expansion e)- final temperature f)- original length

Draw the engineering stress-strain curve for (a) bcc; (b) fcc metals and mark important points.
